Building information modeling in elevated transit viaducts by using parametric revit families

Original work done by Naresh Kumar

Rendered View of BIM Model

This is one of my BIM development work for elevated transit viaduct in revit by generating parametric box girders where we can rapidly change section sizes of box girder flange and web properties ,Parametric 3D profile of Prestress tendons where entire cable x,y,z points can be read by generating schedule in revit since all the parameters created as shared.which can be used for whole 3D BIM, Design based Spread sheets with in revit families, 4D BIM and 5D BIM Quantity take off.

Captured View From Revit

Shall be used for entire BIM Workflow like 3d BIM Modelling of Bridges,

4D BIM Construction Sequence Generation by linking with Time line of Naviswork like activation of pres tress cables,Clash Check with cables,

5D BIM Quantification of Prestress segments where the overall discussion can be taken easily don't wait spread quantity work.

Design Based Spread Sheets developed within the content family files for Substructure just input the governing forces check the Design like bearing pressure,area of reinforcement required,pier interaction ratio then provide the reinforcement in revit where now your model now made as design informative also in result of that major dimension mis matches can be reduced.

Part-1 (Parametric Box Girders).

Basically this parametric box girder has done with sweep blend solid and void elements so that we can make tapered box girders combining two different start and end sections.

Using Sweep blend solid element outer box girder has been created with the parameters to control width of deck slab ,width of bottom slab and using sweep blend void element I have created inner subtracting box with controlled length parameters of inner edge bottom flange width, top flange inner edge width.

This Picture Depicts Basic Idea behind This Content Generation File

Combining both of solid and void Sweep elements we can get Parametric controlled box Girder family file uses for segmental box girders bridges,Balance cantilever bridges.Using Base offset of bottom flange command we can create tapered box girders which can be used for balanced cantilever bridge precast or in-situ segments.

Using Base offset of bottom flange command we can create tapered box girders which can be used for balanced cantilever bridge precast or in-situ segments.

Sample segments type created as S1, S2, S3, and S4

S1-End Diaphragm Section

S2-End Taper Section

S3-Mid Taper Section

S3-Mid Runner Section

All the parameters created as shared so that we can reflect in schedules uses volume of Segments, start and end section sizes.

In upcoming blog post: pres-tress parametric Cable families and Design based Spread sheets with in revit families for viaduct substructure will be shared
